Definitions

  • Such an assembly is intended in particular to give access to the trunk of a motor vehicle by opening the tailgate.
  • a user of the motor vehicle can thus easily load and unload, for example, bulky objects from the rear of the vehicle by opening the tailgate.
  • Such a tailgate opens for example by rotating the tailgate which passes from a closed position, substantially parallel to the amount, to an open position, substantially perpendicular to the amount, in which the tailgate extends above the head of the 'user.
  • an assistance device for opening the tailgate arranged to support the effort required for the tailgate rotation between its closed position and its open position.
  • WO 2006/012848 A1 describes for example a device for opening and closing a tailgate, comprising a cylinder rotatably mounted on the upright and on the tailgate and one end is moved on the tailgate or on the upright to open and close the tailgate.
  • Such a device does not give complete satisfaction. Indeed, when the tailgate is in its open position, the cylinder does not give sufficient strength to the tailgate, which can cause damage to it after several openings. Indeed, in the open position, the tailgate has a significant overhang, which significantly solicits the tailgate to keep it in the open position, particularly in its connection with the amount.
  • reinforcements could be added at the level of the tailgate link with the amount in order to increase the robustness of this link.
  • reinforcements increase the mass of the rear assembly and make more complex its structure and therefore its assembly.
  • the device described in WO 2006/012848 also has the disadvantage that the cylinder is in compression in the closed position of the tailgate. This state implies a strong constraint on the tailgate and generates a significant risk of deformation of the tailgate. In addition, this compressed state in the closed position of the tailgate reduces the life of the cylinder.
  • the document EP1403555A2 discloses a rear vehicle assembly according to the preamble of claim 1.
  • An object of the invention is to provide a rear vehicle assembly for opening and closing a tailgate, which has improved features, including better stability when the tailgate is in its open position without adding mass to this rear set.
  • the invention particularly relates to an assembly of the aforementioned type, as defined in claim 1 and wherein the path of the mobile attachment point of the bar extends in the upper part of the tailgate.
  • the support bar is fixed in the upper part of the upright and in the upper part of the tailgate, it is ensured that the support bar participates in the recovery of efforts required to maintain the tailgate in the open position.
  • the connection between the tailgate and the upright is less stressed when the tailgate is in the open position and it is not necessary to provide additional reinforcements at this link.
  • the displacement of the movable attachment point towards the upper part of the tailgate takes place until said movable attachment point is in the vicinity of the axis of rotation of the tailgate.
  • a tailgate 20 of a rear vehicle assembly 10 is illustrated by the Figures 1 and 2 .
  • This tailgate 20 is intended to provide access to the interior of a rear part of a motor vehicle, for example the trunk and / or the rear shelf of the vehicle, from outside the vehicle.
  • the terms “superior”, “high”, “lower” and “low” are defined relative to a vertical axis of the vehicle. Furthermore, the terms “front” and “rear” are considered according to the driving direction of the vehicle.
  • the tailgate 20 of the invention allows to open and close the rear vehicle assembly 10 to allow a user to have access to the interior of the vehicle. So, objects, particularly bulky, can easily be loaded from the outside into the vehicle or be accessible from the outside to be unloaded.
  • the tailgate 20 is secured in rotation, by at least one hinge 22, with a lateral upright 40 of the rear vehicle assembly 10. To Figures 1 and 2 this amount 40 is represented with a precise inclination with respect to the vertical. However, in other embodiments, the post 40 may of course be made with another inclination relative to the vertical or extend vertically, depending on the prerequisites of a given vehicle.
  • the hinge 22 defines a transverse axis of rotation 24 for the tailgate 20, that is to say an axis extending along the width of the vehicle. When opening the tailgate 20, the latter pivots about its axis of rotation 24 upwards and when closing downwards.
  • the axis of rotation 24 extends to the upper end of the tailgate 20 and the upright 40.
  • the tailgate 20 extends between two uprights extending on either side of the tailgate and the The axis of rotation 24 extends from one upright to the other and is defined by the two hinges each connecting the tailgate to one of the uprights.
  • the rear assembly according to the invention further comprises a device for opening and closing the tailgate 20 relative to the (x) upright (s).
  • a device for opening and closing the tailgate 20 makes it possible to assist the passage of the tailgate 20 from a closed position A, shown in FIG. Fig. 1 , in which the tailgate 20 extends substantially parallel to the upright 40 and closes the rear portion of the vehicle, to an open position B, shown in FIG. Fig. 2 , in which the tailgate 10 extends substantially perpendicular to the upright 40 or at an obtuse angle relative to the upright 40, so as to release access to the vehicle interior.
  • the opening and closing device comprises at least one rigid support bar 30 fixed on the one hand to the tailgate 20 and on the other hand to one of the uprights 40.
  • the support bar 30 is for example made of metal material so as to present a significant rigidity.
  • the support bar 30 extends in an upper part of a lateral upright 40 of the rear vehicle assembly 10 and in an upper part of the tailgate 20.
  • This bar 30 is connected by a first end to a fixed attachment point of the lateral upright 40 so as to pivot upwardly and downwardly.
  • the first end and the fixed attachment point are disposed in the vicinity of the upper end of the lateral upright 40.
  • the support bar 30 is further connected by a second end to the tailgate 20 by means of a movable attachment point 32 extending between the second end and the tailgate 20.
  • the support bar 30 has a curved shape adapted to the kinematics of the tailgate between the closed position A and the open position B.
  • This curved shape has the particular advantage of limiting the forces exerting at the mobile attachment point 32 in the vicinity or in the closed position A of the tailgate 20 when opening or closing the tailgate 20.
  • the opening and closing device according to the invention has the advantage of exerting substantially no stress on the tailgate 20 in the closed position A thereof.
  • the support bar 30 has a substantially rectilinear section 37 extending from its first end to an intermediate point 38 and a rounded section 39 extending from the intermediate point 38 to the second end of the support bar 30.
  • the intermediate point 38 is disposed near the second end.
  • the support bar 30 is intended to open and close the rear vehicle assembly 10 by pivoting the tailgate 20.
  • This rigid bar 30 can hold the tailgate 20 stably due to its rigidity and its form.
  • the rigid bar 30 allows the tailgate 20 to be held in the open position B without excessive stress on the hinge (s) 22 despite the overhang of the tailgate 20 in its open position B.
  • the rounded shape of the section rounded 39 of the support bar 30 in the vicinity of the second end forms a support opposing the weight of the tailgate 20 in its open position B and avoiding a return of the tailgate 20 inadvertent to its closed position A. Thus, part of the weight the tailgate 20 rests on the rigid bar 30.
  • the movable fixing point 32 is displaceable in translation in the upper part of the tailgate 40 according to a predefined path 34 extending substantially perpendicular to the axis of rotation 24 of the tailgate 20.

  • the predefined path 34 extends in the plane defined by the tailgate 20.
  • the bar rigid support 30 can be made with a reduced length since it extends between two ends both located in the upper part of the upright 40 and the tailgate 20.
  • the movable attachment point 32 moves in a reinforcing rail 26.
  • This rail 26 extends along the path 34 of the fixing point 32. It is for example made of a metallic material.
  • the vehicle rear assembly 10 is particularly robust, especially when the tailgate 20 is in the open position B, without the need to add reinforcements in the upright 40 and / or in the tailgate 20.
  • the rail 26 is advantageously formed in a reinforced area of the tailgate 20.
  • a reinforced zone has a higher mechanical strength than the rest of the tailgate 20.
  • It is in particular made of a metallic material.
  • it is for example made of a reinforced plastics material, in particular a thermoplastic material reinforced with fibers.
  • the rail 26 is advantageously formed in one piece with the reinforced zone of the tailgate 20. In this case, it is made of the same material as the reinforced zone. This embodiment is advantageous because the forces exerted by the mobile attachment point 32 on the tailgate 20 then apply in a reinforced area of the tailgate 20, which reduces the risk of deformation of the tailgate 20 under the effect of these efforts.
  • the movable attachment point 32 is in mechanical contact with a moving means 36 of the movable fixing point 32.
  • the moving means 36 is an endless screw, for example a metal screw, extending along the predefined path 34 of the movable fixing point 32 and with which the attachment point 32 meshes. Thus, a rotation of the worm causes a displacement of the attachment point 32 along the path 34.
  • the movable attachment point 32 is remote from the axis of rotation 24 of the tailgate 20 when the tailgate 20 is in the closed position A.
  • the movable fixing point 32 is closer to the axis of rotation 24 than in the closed position A of the tailgate 20, as shown in FIG. figure 2 .

  • the tailgate 20 is stabilized by the rigid support bar 30 in its upper part and the effort required to maintain the tailgate 20 in its open position B are taken up by the support bar 30, which has the effect of relieving the hinges 22.
  • Such an arrangement of the rigid support bar 30 at the upper part of the tailgate 20 also has the advantage that the support bar 30 minimally encumbrances the space under the tailgate 20 in the open position B, which facilitates the loading and unloading of bulky objects for the user.

  • the moving means is a worm which is rotated by the motor to move the movable attachment point 32 along its thread.
  • An opening and closing device equipped with a worm requires less force to move the tailgate 20 to its open position B compared to a conventional system using a jack.
  • worm allows a reduction of the force required for the opening of the tailgate 20. This reduction depends on the thread of the worm.
  • the force required to effect this movement is lower compared to a conventional system equipped with a cylinder since it is simply to drive the worm in rotation.
  • the motor is less stressed compared to a conventional system equipped with a jack.
  • the engine life is increased compared to a conventional system equipped with a cylinder and the engine can be less power, which also makes it less cumbersome.

  • a worm is less expensive than a cylinder usually used for the vehicle rear assembly 10.
  • An endless screw also allows a better stability when the tailgate is in its open position B. Indeed, the worm is rigid and firmly holds the tailgate open B while a cylinder, whose rod is movable relative to the body, is likely to retract slightly when the tailgate is open, for example if a user is supported .
  • the rigid support bar 30, being rotationally secured by its first end with the lateral upright 40 of the vehicle rear assembly 10 and secured at its second end with the movable fixing point 32, exerts a force on the tailgate 20 when moving the movable attachment point 32 to the upper part of the tailgate 20.
